IMPROVEMENT IN GAUGES.

SPECIFICATION.

To all whom it may concern:

Be it known that I, J onN A. MARDEN, of Veazie, in the county of Penobscot and State Vof Maine, have invented certain new and use 'of the door, and also to cut in the depth that it will be necessary to remove the wood to fit the hinge in flush with the edge of the door and the stile. y

In the accompanying drawing, Figure 1 is a perspective view of the gauge. Fig. 2 is a sectional view of the hanging edge of a door, hinge, and stile, showing .how they are fitted together. Fig. 3 shows the edge of the door and the stile, a little distance apart, each part having been gauged.

To enable others skilled in the art to make and use-my invention7 I will now proceed to describe its construction and operation.

I construct a stock, A, of wood or suitable material, and lit onto it a slide, B, with a setscrew, O, by which the slide shall be readily held in any desired part ofthe length of the stock A. I construct a head-piece, 1),-of brass or any suitable metal or material, and fit and fasten it onto the end of the stock A. This stock is fitted to the head-piece so that the face h of the headlpiece shall be perpendicular to or at right angles with the length of the stock, and the face g of the head-piece shall be parallel with the length of the stock. I form a groove or slot, a, in the head-piece, which h shall hold the tongue t' of the piece E. I construct a piece, E, of brass or other metal, composed of the tongue H and cross-piece E, which is turned up atf to fit the slide B, and is at-' the stock A so that it shall protrude to a suitable length through the slot d. The spur b being stationary in H, and the spur a being held stationary in A by means of the wedge c, whenever the slide is moved backward or forward the spur b will necessarily be moved eX- actly as far from the face h as the face of E at f is moved from the spur a. Consequently, if b is placed at the same distance from h as ais from f when the gauge is closed together, when B is moved to any desired pointthe spur I) will mark just the same distance from any surface against which h, is pressed that a will mark from any surface against which f is pressed. But in hanging a door there must be Y room allowed for the paint; consequently the spur b is placed just enough further from the end t' of the tongue H than the spur a is xed from the face f when the gauge is closed. This causes the spur b to mark just the ldesired distance further from the jamb ofthe door than the spur d marks from the edge of the door; and when the hinge is fitted it keeps the door from touching the jamb by just the desired distance. t

It will readily be seen that if there is a molding on the casing of the door, as at o,

then any gauge working from the casing could not be applied. And there may be said to actually be no way to gauge they stile for hinges but by some gauge which Ashall Work against the jamb and tit into the corner formed by the jamb and stile. Gauges with two spurs are common; but both gauges operate independently of the slide. One spur is generally made stationary near the end of thestock, and the other spur is generally made stationary in a sliding tongue running through the slide, and adjusted by a screw in the other end of the stock, so as to be moved either toward the end spur or away from it, independently of the slide. Such gauges will mark parallel lines, but cannot -be used to mark for tting one side of a hinge to the stile and the other side to a door 5 nor can one spur be applied by tting into a corner to make a mark at a desired relative distance from that corner that another spur on the same gauge shall mark by fitting over a projecting corner. This is fully shown in Fig. 4, which is a sectional view of this gauge, showing the end D iitting against the jamb 1, the spur bmarking the stile F, while ATENE OFFICE.

of the door.

the face f of the slide B presses against the side of the door, and the spur a marks the edge The head D serves to keep the stock at right angles to the jamb, and also to keep the tongue H fiat against the stile, thus insuring a good and correct gauge by the spur b.

I do not claim as my invention the stock or stile, or the parts common to other gauges; but

What I do claim as my invention, and desire .to secure by Letters Patent, is-

1. The tongue H, formed With the head-piece or cross-head E, slot d, and spur b, and attached to and moving with the slide B.-

2. The head-piece D attached to the stock A, and formed with the slot u to hold the tongue H, and having the faces h and g at right angles to each other.

3. The combination of the stock A, slide B, tongue and cross-piece H E, spur a, spur b, and head-piece D, substantially as and for the purposes shown and described.
